1 Claim.

The invention relates to railway cars having an openable panel, such asa window, which is, when closed, oblique to an adjacent panel. Such acondition frequently arises in stream line cars, where abrupt surfaceangles are to be avoided, and in which, especially in the drivers cab,the space is too limited to admit of the use of swinging sash.

The object of the invention is to provide for the mounting of a windowsash in such an ablique panel in such manner that while it may be snuglytted within the window openingr when closed, it may be readily opened byslight turning, followed by a lateral sliding movement.

One embodiment of the invention is hereinafter described, and. isillustrated in the accompanying drawings, in which Fig. 1 is an endelevation of of the improved car;

Fig. 2 is a detail side elevation of the front portion thereof; f

Fig. 3 is a plan section on the line 3 3 of Fig. 1;

Fig. 4 is a detail inverted section on the line 4--4 of Fig. 1;

Fig. 5 is a detail section on an enlarged scale, taken from the samepoint of View as Fig. 4; and

Fig. 6 is a detail section on an enlarged scale on the line 6 6 of Fig.3.

The car body I0 is designed with view to reducing air resistance,particularly when traveling at a high rate of speed. Its forward end ispreferably of rounded contour, as indicated in Figs. 1 and 2, andincloses a compartment or cab for the engineer or driver, thiscompartment being provided with a central forwardly looking window II,and lateral windows I2, I3, located in the backwardly and laterallysloping walls of the front end of the car. These windows, certainlythose designated I2, I3, are desirably openable. The compartment beingnecessarily restricted in size, it is essential that the window sash bemounted for sliding movement. Because of the curved orpanel form of thecar wall, both horizontally and vertically, and the necessity forsecuring a close t for the window when closed, an ordinary slidewaycannot be used.

'Ihe framing of the car, as indicated at I4, is formed of tubing, and iscovered and lined with sheet metal sheathing I5, I 6. The frame I'I, I8,for the window I2 is desirably of metal, and is secured to the car wallpreferably by screws enteringA frame elements, as I4, as plainly shownparticularly in Fig. 5. The inner face of one of the'stiles of thewindow frame I'I is preferably substantially normal to the section ofthe wall to which it is attached, that of the opposite stile I8,however, being slightly oblique to the plane of the wall, theinclination being toward the window opening from the inner to the outermargin of the face.

The window sash may be of any suitable form and structure, providing itwill t within the casing; and, as shown, it comprises a pair of 10 stileelements I9, 20, and top and bottom rails 2I, 22, outer stops 23, 23,for the glazing and an outer sheet metal molding 24 covering the outerfaces of the elements 2|, 22 and 23, these parts being secured togetherby any suitable 15 means, such as brazing. The glazing 25 is preferablymounted in a molded frame 26, and secured against the stops 23, 23, bymeans of a sheet metal stop'2l, secured to the sash frame, as by meansof screws 28.

The sash is openable by a pivotal, followed by a lateral movement. Atrack is provided for carrying the sash laterally, and in a pathinclined away from the plane of the casing, the sash being swung aboutone of its stiles into and out of the casing.

In its broader aspects the invention includes any form of track disposedas above, and any form of connection between the sash and track whichwill permit the pivotal movement of the sash into and out of its casing,and its longitudinal movement along the track.

In the illustrated embodiment of the invention, each of the top andbottom sash rails 2|, 22, is provided with a pair of instanding lugs 29,30, and 3l, 32, located, respectively, as shown, near the sash stilesI9, 20. Each of these lugs carries a pivot bolt 33, 34, projecting,respectively, upwardly and downwardly, and upon which are mountedanti-friction rollers 3.5, 36, preferably slightly conical in form.Track plates 3l, 38, are mounted, respectively, above and below thewindow opening, and each is provided with a straight slot 39 forreceiving the rollers 35, 36. These track plates are secured to the carwall 45 by means of sheet metal brackets 40, 4I and. extend along theinner face of the wall section 42, which is next adjacent and to therear of the window I2. The track slots 39 terminate a short distancefrom the forward sash stile I9, and are aligned with the inner marginthereof.

A lateral slot 43 extends from the slot 39 to` ward the window casing,and is spaced, approximately, at both ends from the inner end of theslot 39 correspondingly with the spacing of the lugs 29, 30. The slot 43is inclined backwardly toward its inner end, corresponding approximatelywith the inclination of the inner face of the casing element I8.

When the window is open to its full extent the sash occupies theposition shown in dotted lines in Fig. 3. In closing the window the sashis moved to the right (Fig. 3) until the roller 36 carried by the lug 3|reaches the end of the slot 39, the sash stile then making contact withthe inner margin of the casing stile, and the roller carried by the lug32 being now opposite the slot 43. The sash now being swung about theroller 36 as a pivot, the roller carried by the lug 32 moves to theinner end of the slot 43, and the Window is snugly closed. Any suitablelocking means may be employed for holding the sash in closed position. Ahook 44 may be secured to the stop 21 for convenience in moving thesash.

While the construction shown and described is highly efficient, variouschanges may be made therein Within the scope of the appended claim.

I claim as my invention- A railway car having a pair of adjacent Wallpanels relatively oblique, a window opening in one of such panels, alaterally openable sash for such opening, a straight track extendingfrom adjacent the remote side of the Window casing and overlapping thecompanion panel and spaced therefrom, a lateral track extending from themain track toward the opening and being inclined toward the remote endof the main track, and pintles secured to the sash adjacent its sidesfor engaging the tracks, the pintle engageable With the lateral trackbeing so 1ocated that as it approaches the remote end of such track itwill urge the remoter sash stile against the casing.
